Abstract (en)
[origin: WO2020127288A1] The invention relates to a hologram master (10) for producing customised holograms (400) with kinetic diffraction patterns (32) comprising: a continuous customisation region (20), which comprises at least one first diffraction region (30) having a mirrored blaze grating (31) with kinetic diffraction patterns (32) integrated therein or thereon. The invention further relates to a method for producing security holograms (400) using a hologram master (10) of this kind and to security holograms (400). The advantage consists in the fact that the presence of kinetic diffraction patterns (32) in the at least one diffraction region (30) is not detrimental to customisation.
